kubeadm: preflight check for incorrect FQDN
**What this PR does / why we need it**: There are a variety of system configuration errors (such as cloud-init bugs when deploying on AWS) which can cause hostname and uname -n to be wrong for a given host. This will cause kubeadm setup to fail in interesting and hard-to-figure-out ways (it doesn't fail until you start trying to set up DNS on the master, for example).
This PR adds a preflight check to test whether or not the server can reach itself using that name. This does not catch the case that the FQDN belongs to a different but valid server, but it would catch some of the cases.
**Which issue this PR fixes** : fixes https://github.com/kubernetes/kubeadm/issues/135

Add bootstrap cluster role for external pv provisioners
The set of permissions an external provisioner https://github.com/kubernetes/kubernetes/pull/30285 running as a pod will need. Technically in order to dynamically provision PVs one doesn't need to "update" PVCs or "watch" events but the controller https://github.com/kubernetes-incubator/nfs-provisioner/tree/master/controller we are recommending people use does those things to: set lock annotations on PVCs and watch `ProvisioningSucceeded`/`ProvisioningFailed` events.
Some external provisioners may need additional permissions, for example nfs-provisioner requires "get" access to Services and Endpoints when run "statefully." I think in that case we would recommend creating a new ClusterRole specific to that provisioner, using this as a base?
(This was to be a part of my redo/fix of the external e2e test https://github.com/kubernetes/kubernetes/pull/39545 but I'm submitting it as a separate PR for now due to some issues I had with running nfs-provisioner on gce.)

move api server no kube dep packages
Simple moves, see commit titles. I did not move the source of the generated swagger, I simply change the destination of the script. I'm ok building a little debt to complete the move.

securitycontext: move docker-specific logic into kubelet/dockertools
This change moves the code specific to docker to kubelet/dockertools,
while leaving the common utility functions at its current package
(pkg/securitycontext).
When we deprecate dockertools in the future, the code will be moved to
pkg/kubelet/dockershim instead.

kubeadm: Move some code from apiclient.go to the dedicated apiconfig phase
**What this PR does / why we need it**:
Add constants and somewhat refactor the RBAC code as well + some cleanup.
I'm planning to rewrite the code in `setupmaster.go` later, but this PR has only the move of the code for easier reviewing.
**Special notes for your reviewer**:
This is broken out from: https://github.com/kubernetes/kubernetes/pull/40556

This commit wires-in the pre-existing `--container-runtime` flag for
local node_e2e testing.
This is needed in order to further skip docker specific testing
and validation.
Local CRI node_e2e can now be performed via
`make test-e2e-node RUNTIME=remote REMOTE=false`
which will also take care of passing the appropriate arguments to
the kubelet.

Use full package path for definition name in OpenAPI spec
We were using short package name (last part of package name) plus type name for OpenAPI spec definition name. That can result in duplicate names and make the spec invalid. To be sure we will always have unique names, we are going to use full package name as definition name. Also "x-kubernetes-tag" custom field is added to definitions to list Group/Version/Kind for the definitions that has it. This will help clients to discover definitions easier.
Lastly, we've added a reference from old definition names to the new ones to keep backward compatibilities. The list of old definitions will not be updated.
**Release note**:
- Rename OpenAPI definition names to type's full package names to prevent duplicates
- Create OpenAPI extension "x-kubernetes-group-version-kind" for definitions to store Group/Version/Kind
- Deprecate old definition names and create a reference to the new definitions. Old definitions will be removed in the next release.
Prepares for allowing encryption at rest of resources as well as any
other lower level optimization we might chose to implement.
Also cleans up a bunch of ugly code.
This fix prevents the PV controller from forcefully overwriting the provisioned volume's name with the generated PV name. Instead, it allows dynamic provisioner implementers to set the name of the volume to a value that they choose.

sync client-go
Our first straight mechanical sync! `client-go/pkg` looks nice and slim, we're authoritative for all other packages.

- split out port forwarding into its own package
Allow multiple port forwarding ports
- Make it easy to determine which port is tied to which channel
- odd channels are for data
- even channels are for errors
- allow comma separated ports to specify multiple ports
Add portfowardtester 1.2 to whitelist
